Don't miss out on the "Carolina Keeper" (also available at BPS). If you're using over 1/2 ounce weight, you may want to put two on, so the weight doesn't slide them back. I've been told not to use on very light line because they can nick the line, but never seen it personally.
With the peg, you lose the sliding feature of a carolina rig, and would have a quicker rigging using a split shot.
The new 3x baits float VERY well, and Gene Larew had a few special floating baits at the tackle show recently.
I'm thinking a Carolina-rigged Senko popped, rather than dragged slowly, might really be a hot bait.
